' SAFETY-PIN.

5 State of Arizona, have invented certain new and useful Improvements in Safety- Pins, of which the following is a specification. v

This invention relates to certain'new and useful improvements in safety pins of that class provided with a shield or the like whereby it is adapted for use in laundry work, in rough-dry work and wet wash, for

tagging socks and, in fact, any and every use to which a pin of this character could be put in a laundry to save the expense of marking, as well as all other uses for which it is adapted. v

The present invention has for its objects safety pin of th1s general character which will not catch on objects it comes in con- Z tact with, such ashooks and eyes on cloth- I a ing, and yet which will be suflicientlystrong ,25 be put and not be twisted out of shape by the weight of the wet clothing or hard usage.

desired. It is equally as well adapted for household use and maybemade as fanciful accidentally removed, but yet permitting it as may be desired. Other objects and advantages of the m- ,vention will hereinafter appear and the novel features thereof willbe pointed out in' the appended claimsaccompanying drawings, which, with the numerals of reference marked thereon, form apart of this specification, "and in which- "Figure 1 is a face view of my improved vsafety pin.

Like numerals of referenceiindicate like parts throughout the several views.

Referring to the drawings, 1 designates a pm of wire of any well-known form adapted for the purpose having a pointed end 2, as usual, the other end being-bent at an angle, as at 3, to enter a hole 4 in the shield so that when it is in place and the blank from which the shield and guard are formed 1s pressed together it will ,be rigidly held in place.

The shield and guard may be formed of any suitable material, but preferably of a slngle piece of thin flat spring material, such as shown at 5 in Fig. 4. This material is bent along the line 6 to form the tongue 7,

the bend being preferably rounded, as

-of the pin 1 is inserted inthe hole 4, the

blank is bent over the same and the adjacent portion of the fixed member-of the 'pfln and .1

pressed together, being soldered, necessary, or otherwise fixedly held in position,-and then the blank is bent along the .line 6 forming the tongue 7 which overlaps the guard member 9,

as seen clearly in Figs. 1 and 3.

The tongue 7 is normally bent outwardly at'an angle 'from the shield portion-5 and theinherent resiliency of the guard member 9 normallycauses the same to flex outwardly and engage the under surface of the guard,

as "seen in Fig. 3. The free end of the guard 1 member is beveled upon the inner surface, as seen at 10, to prevent the pinfrom catching on the edge and possibly forcing itself out of the shield when any undue pressure is put upon it. .'I may sometimes roll out the guard end from its point of connection with the shield member so as to make it more flexible, thus me to make the shield of heavier allowin materia so that it will be stronger and yet preserve the. requisite resiliency in the guard. -The guard ispreferably substan- ,tially the same width as the shield'so as to make it more substantial and less liable to be twisted out of shape and at the same time 5 is an end view s insuring greatest strength.

In practice, after the pointed end of the pin has been forced through the material,

itis allowed to engage the guard 9 when the outward pressure on the pin caused by the coil 11 thereof will force the pin point in the direction of the arrow in Fig. 1 until it passes the free edge of the guard, the pressure forcing the guard inward to permit ard, when the latter springs left hand on the guard, as seen in Fig. 5, and pressing it inward, {when with the right hand the'pin may be forced downward and outward by the free edge of the guard, as seenin Fig. 5, which makes the operation convenient and simple and one 1n which 1 'As' soon as the'pin point has passed the free the tongue.
